J-B Weld FiberWeld Repair Cast

Repair Cast is a high-strength fiberglass wrap, impregnated with a specially-formulated resin to repair pipes up to 1" (or 2" with that kit) in diameter. When activated by water, the product forms a strong, waterproof bond that hardens like steel in 15 minutes. The kit includes an epoxy putty stuck for additional sealing strength.
